As said before, the JK does not utilize a SYE. RE does have CV driveshafts and adapter yokes that have been available for over a year now.Looking for a good SYE for a 2007 2 door. I like the RE SYE, but i'm told it's not available yet. Any suggestions or alternatives? Is a SYE really needed for a 3.5" RE suspension lift? Thanks for the feedback!
